The ‌JOYO ZGP-W is a compact power converter designed with guitar effects in mind. It can turn a charger or power bank into a power supply for guitar effects in the blink of an eye. Besides, it can be installed to effects or other devices, providing stable and clean voltage. The product includes a USB cable in the set, which can be used to obtain DC9V voltage - by connecting the charger or power bank to the ZGP-W. The output current measures 400mA - this is a satisfactory value for powering digital effects. The ZGP-W is distinguished by a special circuit that filters out all interference and gives a clean signal. This product features reverse polarity, overload, high and low voltage and short circuit protection. If there is any threat, the LED will turn off automatically and all connected devices will be completely safe. ZGP-W supports a wide range of voltages and is made of the highest quality materials that ensure stable operation.
